Abstract
Provided are example methods and systems for treating a subterranean formation. An example method comprises alternately pumping a volume of proppant-laden fluid and a volume of spacer fluid into a wellbore penetrating a subterranean formation. The proppant-laden fluid comprises an aqueous fluid and proppant. The spacer fluid comprises an aqueous fluid. At least one of the proppant-laden fluid or the spacer fluid comprises a synthetic clay. The volume of proppant-laden fluid and the volume of spacer fluid may be pumped in any order. The method further comprises repeating the alternately pumping a volume of proppant-laden fluid and a volume of spacer fluid at least once.
